My invention relates to containers. It has to do, more particularly,that is formed primarily of such material as ber board, pulp board, orpaper or straw board, al though it is not necessarily limited thereto.`More specically, it relates to the bottom structures of a container ofthe type indicated.

One of the objects of my invention is to provide a fiber barrel orcontainer of such a nature that the bottom head will be securely held inposition and the associated chime structure will be of such a naturethat it will withstand the excessive blows to which a container of thistype is subjected in normal use.

Another object of my invention is to provide a ber barrel structure orcontainer having the bottom head applied thereto in such a manner thatthere will be a tfluid-tight seal between the bottom head and thecooperating body portion of the barrel.

Another object of my invention is to provide'a ber barrel structure orcontainer having a bottom head so constructed that its inner portion isof iiber material but its outer portion is of metal and thus thecontents of the container will not contact with the metal but still themetal will protect the ber portion from scufiing or other injury.

In its preferred for-m, my invention contemplates the substantiallycylindrical body portion which is made of fiber board or other similarmaterial and which has open ends. A head or disk of heavy ber materialis placed in the lower end of the body portion. Then a suitable metaltray is positioned on the end of the body portion below the fiber disk.This metal tray, consists of a disk-like portion which lies within thebody portion beneath the iiber disk and which has a peripheral iiangethat extends outwardly, along the inner surface .of the body portion.around the ends of the body portion and then towards the top of the bodyportion, along the outer surface of the body portion. The ber bodyportion together with the metal tray are bent to form a continuousinternal groove, the walls of whi'ch tightly embrace the top and bottomsurfaces of the fiber disk adjacent its periphery. This also produces a.continuous external groove in. the body portion and ange of the metaltray at a point spaced above the ber head or disk. This serves toprovide a resilient joint which will effectively withstand the shockapplied to the lower chime and prevent crushing of the chime. The lowerend of the container will be enclosed by the provision of a containercomprising a i with a barrel or container ture.

body -portion.

continuous metal tray and will, therefore, be completely moisture-proofeven though it stands in water. Furthermore, the metal tray will protectthe fiber disk or head and the lower end of the fiber body portion frominjury.

lThe preferred embodiment of my invention is illustrated in theaccompanying drawing wherein similar characters of reference designatecorresponding parts and wherein:

Figure l is a detail, in vertical section, of the lower end structure ofa container made according to my invention.

Figure 2 is a similar view showing the parts of the end structureassembled and ready for a nal forming operation to produce the structureo Figure 1.

Figure 3 is a side elevation, partly broken away, illustrating the lowerportion of a container having the end structure of my invention.

Figure 4 is a view similar to Figure 1 but showing a modification of mystructure.

With reference to Figure 3 of the drawing, I have shown a barrelstructure comprising a body portion l which may be of suitable fibermaterial. This body portion is preferably of cylindrical form and may beproduced in any desired manner.

As indicated in Figures l and 3, when the lower head structure isfinally completed, it embodies i a disk-like fiber head 2 which is heldin. position within a continuous internal groove 3 formed in the lowerend of the body portion. A continuous external groove 4 is formed abovethe head in the body portion to provide a resilient chime struc- TheAfiber head 2 has its lower surface protected by a metal tray member 5which has a main disk-like portion 6 that lies beneath the member 2. Thetray member 5 also includes a peripheral ilange portion 'l which extendsdownwardly, around the end of the body portion l and then upwardly alongtheouter surface of the This ilange 'l is bent with the body portion lto produce the internal groove 3 and the external groove l.

In forming this bottom head structure, as indicated in Figure 2, thedisk 2 is inserted into the lower end of the cylindrical shell or bodyportion l. This disk `2 is preferably made of heavy ber material similarto the shell I and is just slightly smaller in diameter than the shelll. A tray 8 of light fiber material is also inserted into the lower endof the shell l below the disk 2. This tray 8 embodies va disk-like bodyportion and a downwardly extending peripheral flange 9 which extendsalong the inner surface of the shell l.

The metal tray 5 is then positioned on the lower end of the shell orbody portion I. 'I'he disk-like portion 6 thereof will support the iberdisk 2. The ange 1, at this time, will be U- shaped in cross-section andwill extend downwardly, around the end of the shell I, and then upwardlyinto overlapping relationship with the outer surface of the shell I. Itwill be noted that the outer portion of iiange l extends a considerabledistance above the disk 2j Thus, the metal tray forms a'continuous metalmember having a channel therein which receives the lower end of theshell I'. It will be noted that the ange 9 of the light ber tray 8 alsoextends into the channel formed in the flange 'I of the tray 5.

'I'he assembled unit indicated in Figure 2 is then subjected to a ilnalforming operation. This iinal forming operation will bend the iber bodyportion or shell I together with the flange I of the metal tray 5 in themanner indicated in Figure 1. The lower end of the body portion or shellI together with the flange 'l of themetal tray 5 is bent intooverlapping relationship with the outer surface or bottom surface of thehead 2. The lower U-shaped portion I of flange 'I and the extreme, lowerend of the body portion I will be curled or beaded, as indicated at I I`in Figlure 1, and will be forced into the lower`surface of thecooperating disk or head 2 and tray 8, forming therein a continuousgroove I2 which is spaced slightly inwardly from the edge of the disk 2.This gives a bulging action at the point I3 which adds further to thetightness of the joint.

When the body portion or shell I and the flange 1 are simultaneouslybent, the external groove 4 is formed therein. By forming thiscontinuous external groove 4, there is produced an inwardly projectingrib I4 which is spaced from the end of the body portion and againstwhich the disk 2 is clamped. It will be apparent that the continuousinternal groove 3 is formed which receives the head or disk 2 andtightly embraces it. By forming the external groove l, a resilient chimestructure is produced. Any blow applied tothe lower end of the containerat the point I will merely serve to cause the walls of the groove 3 tomore closely approach each other and grip the head structure 2therebetween; Moreover, the walls of the external groove 4 will iiextowards each other and will absorb the shocks applied to the end of thecontainer. The metal tray 5 will completely cover the bottom of the:liber head 2 .and will extend around the lower end of the body portionI. Thus, the fiber end 2 and the lower end of the body portion I will beprotected from injury by a continuous enclosing metal member.Furthermore, the continuous metal member 5 will produce an absolutelymoisture proof lower end structure. In fact, the lower end of thecontainer may stand in -water without leaking. Also, the lower end ofthe container will be vapor proof in that escape of vapor from thecontents of the container through the bottom head structure will beprevented. Also, it will be apparent that although the ber head 2 hasits outer surface protected by metal, the

contents of the container will not'contact with metal.

In Figure 4, I illustrate of my structure. In this separate members.However, the function or the structure will be substantially the same asbefore with the exception that there will be a joint I6 between thesemembers. Howthis joint will be effectively sealed. 'I'he lower end ofthe body portion Ia and the disk 2a will be effectively protected.

It will be apparent from the` above description that I have provided aber barrel structure of nature that the bottom head is securely held inposition and the associated chime structure is of such a nature that itwill withstand the under the most unfavorable conditions.

Various other advantages will be apparent from the precedingdescription, the drawing and the following claims.

Having thus described my invention, what I claim is:

1. A container structure comprising a body portion made or ber board orthe like, a barrel head inserted in and said body portion.

3. A container structure according to claim 1 wherein the ange anddisk-like portion of theh metal tray are separate members.
